In recent years, China's plastics extrusion molding processing have greater progress.
But in practical production is still has many problems, the following by changshu smoothly da plastic products factory is introduced in the production process under the influence of plastic extrusion forming of the three major factors.
1. The stand or fall of forging material difference. Because of long time work under high temperature and high pressure environment demand, of plastic injection mould heat particularly high abrasion resistance and the request of the patient, the traditional extrusion mold by using 3 cr2w8v steel mold is low because patience can't thermal defects, by high temperature resistance and abrasion resistance good 4 cr5mosiv gradually replaced steel mold, and according to real data statistics, 4 cr5mosiv steel mold the use life of two to four times as many than traditional steel.
2. Quenching technology optimization. Quenching technology from the early produced extrusion die mould for preheating, the lack of regulation mold internal microscopic is the pretreatment of quenching technology, after high temperature quenching and oil quenching cooling two to two and a half hours, to temper the workpiece processing, select heats up evenly heating technique, remove the internal stress generated quenching. Each of these steps are carried out demand tightly controlled accurately, to ensure that mold the use of the life.
3. The reasonable planning of plastic injection mould. Tooling planning scheme is reasonable, using the standard mold structure, planning out the fit the mold production technical and feasibility. Extrusion die of the planning scheme is applied progress and produce the main steps in the quality of life, and work together with purchasing department and technology department, complete the mold structure can use sex, the stand or fall of mold parts, technical standards of machinability.
